Note

The following content was generated by AI.

Renames ## Upcoming version to ## 0.2.0 (2026-09-25) and edits it into release notes: a summary paragraph, the one break (#1765 refuses answers and archives that 0.1.0 wrote), and the four PRs since 0.1.0. Merging tags v0.2.0 and publishes to PyPI.

Checks

The version is a minor bump because #1765 breaks reading archives that 0.1.0 wrote, and AGENTS.md says a release that breaks a model file raises the minor version.

Checked:

• python -m tools.changelog check: releases 0.2.0 on merge.
• python -m tools.changelog pending: 0.2.0.
• main at 9870a3b carries all four PRs. Its CI state is whatever GitHub shows; I did not re-run the suite for a changelog-only diff.

Not done: the branch keeps its name claude/release-0.1.1, which nothing reads. The merge and the pypi environment approval are yours.
